Abstract: About half of the Russian Arctic coastline consists of ice-rich permafrost deposits. The dynamic response of this coastal type is forced mainly by the change of natural environment caused by the development of global warming. Rising temperatures are altering the arctic coastline and much larger changes are projected to occur during this century as a result of reduced sea ice, thawing permafrost. Less extensive sea ice creates more open water, allowing stronger wave generation by winds, thus increasing wave-induced erosion along Arctic coast. Technogenic impact can also influence the rates of their erosion, causing rapid retreat. For key areas on the coasts of the Russian Arctic Seas, connections between climate change, human activity and coastal erosion have been analyzed.
